The invention discloses a control method for improving the driving comfort of an adaptive cruise system. The control method comprises the following steps: 1) carrying out preliminary screening processing on vehicle natural driving data collected by a camera; 2) according to the screened data, performing curve fitting on the data to obtain a speed-acceleration extreme value range relation curve; 3) establishing an adaptive cruise system model based on a model predictive control algorithm through the input and output relationship of the adaptive cruise system; (4) the performance target of the self-adaptive cruise system is restrained, the speed and the distance adopt a restraining mode of a conventional model predictive control algorithm, and aiming at the driving comfort of the self-adaptive cruise system, variable acceleration restraining along with the speed change is provided for the target acceleration, so that the driving comfort of the self-adaptive cruise system is improved. The specific constraint value is the speed-acceleration extreme value range curve obtained by fitting in the step (2). Finally, the effectiveness of the method is verified through Matlab simulation software.

    本发明公开了一种提高自适应巡航系统驾乘舒适性的控制方法,包括如下步骤:1)基于摄像头采集的车辆自然驾驶数据对数据进行初步的筛选处理;2)根据筛选处理后的数据,对数据进行曲线拟合,得到速度‑加速度度极值范围关系曲线;3)通过自适应巡航系统的输入输出关系,建立基于模型预测控制算法的自适应巡航系统模型;4)对自适应巡航系统性能目标进行约束,速度和距离采用常规模型预测控制算法的约束方式,针对自适应巡航系统的驾乘舒适性,本发明提出对目标加速度进行随速度变化的变加速度约束,具体的约束值为第2)步中拟合得到的速度‑加速度极值范围曲线。最后通过Matlab仿真软件验证了本发明的有效性。
